PROP-BLOCKFOR VEHICLE-TOPS.

SPECIFICATION forming part of Letters Patent N o. 720,625, dated February 1'7, 1903.

Application iilecl October 11,1902. Serial No. 126,928. (No model.;

4 the following is a specification.

My invention relates to improvements in carriage prop-blocks; and it consists in a certain peculiar prop-block, the novelty, utility, and practical advantages of which will be fully understood from the followingr description and claims when taken in connection with the accompanying drawings, in which- Figure l is a side elevation of a bugg bodyequipped with my improved prop-block;

Fig. 2, an enlarged detail transverse section taken in the plane indicated by the broken line 2 2 of Fig. 1 and illustrating the improved prop-block; Fig. 3, a section taken at right angles to Fig. 2 and in the plane indicated bythe broken lline 3 3 of said gure, and Fig. 4 a side elevation of the body of the prop-block as it appears when wrapped with wire.

Similar letters of reference designate corresponding parts in all of the several views of the drawings, referring to which- A'is a buggy-body; B, a shifting rail arranged on the body; C, an arm or bolt of angular form in cross-section extending laterally from the shifting rail and having its outer end reduced and threaded; D, a bow pivotally connected to the gooseneck of Ythe shifting rail; E, a bowsupport pivotally mounted on the reduced end of the arm or bolt C and held in position by a nut F; G, a leather washer arranged on the arm or bolt C and against the shifting rail, and Ha leather washer also arranged on the said arm or bolt, but against the prop E. All of these parts may be and preferably are of the ordinary well-known construction.

I is my improved prop-block, which is arranged on the arm or bolt C, between the washers GH, after the manner best shown in Fig. 2. This block in the preferred embodiment of my invention comprises a body a, formed of wood and having a bore h of angular form in cross-section to snugly receive the arm or bolt C, a piece of wire @,Wound or coiled around the body and havingits whirls embedded therein and its ends connected thereto, and a covering d, of leather or other suitable material, surrounding the wirewrapped body. When desired, the propblock may also comprise the usual cushion e, composed of a filler covered with leather; but said cushion forms no part of my invention,

and I do not desire to be understood as con- Volving a departure from the scope of myinvention.` Y

Y The bodies of prop-blocks have heretofore been formed of Wood, because of the cheapness and lightness of such material and the facility with which it may be reduced to the shape desired. Such bodies, however, have been found to be objectionable, because after a short period of use they crack and'spread and finally drop off the arms or bolts onwhich they are mounted. My improved propblock body formed of wood and wrapped with wire or other suitable material may be produced almost, if not quite, as cheaply as the ordinary body formed of wood alone, and yet it -is materially advantageous as compared with the ordinary body, since in virtue of a piece of wire, metal tape, 'or other suitable material being coiled about the wood cracking-or spreading of the wood is precluded,- and the usefulness of the body and the prop- VVblock Yas a whole is materially prolonged.

The embedding of the whirls of the Wrapping in the surface ofthe wood body in the manner shown and described is advantageous, since when the body is covered With leather the exterior of the prop-block is smooth and finished in appearance.

Having described my invention, 'what I claim, and desire to secure by Letters Patent, 1s-

l. As an improved article of manufacture, a prop-block comprising a body formed of Wood, and a piece of wire, metal tape or other IOC suitable material, coiled a number of times about the body, and connected at its ends thereto.

2. As an improved article of manufacture, a prop-block comprising a body formed of wood, a piece of Wire, metal tape or other suitable material, coiled a number of times about the body, and connected at its ends thereto, and a covering of leather or other suitable material arranged on the Wrapped body.

3. As an improved article of manufacture, a prop-block comprising a body formed of wood, a piece of Wire, metal rape or other ROBERT C. SGHEMMEL. Witnesses:
